Sec. 29-237. (Formerly Sec. 19-434). Inspection.
Sec. 29-237. (Formerly Sec. 19-434). Inspection. All boilers included under this
chapter shall be inspected by a state boiler inspector or by a special inspector employed
by an insurance company licensed to insure boilers in this state as follows:
(1) Power boilers, meaning boilers operating at steam or vapor pressures in excess
of fifteen pounds per square inch gauge, except power boilers that operate with internal
water treatment under the direct supervision of a qualified engineer, shall be inspected
each year. Such boiler inspection shall consist of (A) a thorough internal and external
inspection while not under pressure, and (B) an external inspection under operating
conditions not more than six months after the internal and external inspection. No more
than fourteen months shall elapse between internal inspections and between external
inspections while under pressure.
(2) Power boilers that operate with internal water treatment under the direct supervision of a qualified engineer shall be inspected every eighteen months. Such boiler inspection shall consist of (A) a thorough internal and external inspection while not under
pressure, and (B) an external inspection under operating conditions not more than nine
months after the internal and external inspection.
(3) Where construction will permit, low pressure steam or vapor heating boilers, hot
water heating boilers, hot water supply boilers and hot water heaters shall be inspected
externally biennially and internally at the discretion of the boiler inspector. If a boiler
inspector decides a hydrostatic test is necessary to determine the safety of a boiler or
heater, such test shall be made under the inspector's direction. The Commissioner of
Public Safety may order inspections by the Department of Public Safety or the insurance
carrier in addition to the regular annual or biennial inspections to clear up any doubts
as to the safety of continuing the operation of any boiler or heater included in this chapter.
Each boiler insurance carrier shall forward to the commissioner, not later than thirty
days after each inspection as required by this chapter, a report of such inspection upon
appropriate forms as promulgated by the commissioner, who may use the form suggested
by the American Society of Mechanical Engineers.

department of public safety in Subsec. (b), effective January 1, 1979; Sec. 19-434 transferred to Sec. 29-237 in 1983; P.A.
85-6 amended Subsec. (b), providing that low pressure steam or vapor heating boilers, hot water heating and supply boilers
be inspected internally at the boiler inspector's discretion, where previously both internal and external inspections were
required "where construction will permit"; P.A. 86-83 amended Subsec. (b) to require inspection of hot water heaters;
P.A. 99-138 redesignated former Subsec. (a) as Subdiv. (1), added Subdiv. (2) re provisions for inspection of boilers that
operate with internal water treatment under the supervision of an engineer and redesignated former Subsec. (b) as Subdiv.
